## Description

desertcart.com: Medik8 C-Tetra - Balancing Vitamin C Serum For Face - Smooths Fine Lines and Wrinkles - Face Serum with Squalane - Vegan and Gluten Free - 1.0 oz : Beauty & Personal Care

Review: Light weight, radiant and balanced results - Medik8 C-Tetra Advanced has become one of my go-to morning serums. I love that it delivers all the brightening benefits of vitamin C without the irritation or heaviness that stronger formulas can sometimes cause. The texture is a lightweight gel-serum that absorbs quickly and layers beautifully under moisturizer and SPF—no stickiness, no pilling. Within a couple of weeks of consistent use, my skin looked noticeably more radiant and balanced. I also noticed a subtle plumping effect, especially through the cheeks, and my skin felt well-hydrated throughout the day. It gives that healthy, lit-from-within glow rather than an artificial shine. What really sets this serum apart for me is how gentle yet effective it feels. Even with daily use, my skin barrier stayed calm and happy, which isn’t always the case with vitamin C. It’s a great option if you want visible brightening, hydration, and antioxidant protection without compromising comfort. Overall, Medik8 C-Tetra Advanced feels like a smart, elevated vitamin C—perfect for everyday use and especially great if your skin prefers a more balanced, modern formulation.

## Questions & Answers

**Q: what percent of the ingredients is tetrahyxyldecyl ascorbate?**
A: The C tetra is 7% THD ascorbate and the C Tetra Luxe is 14%. I emailed the company back about a year ago and this is what they told me. I’ve switched to a very similar one from ghost democracy that is 18% THD and doesn’t have the fragrance/essential oils because that was irritating my skin. It has the same dry oil like texture as medik8

**Q: Es duradera oh tiene corto tiempo de vida ,ocea se oxida rapido?o**
A: Esta bueno

### ⭐⭐⭐⭐⭐ Gentle, Effective, and Great Value – My Go-To Vitamin C Serum
*by R***N on March 25, 2025*

I’ve purchased this serum three times in the past 15 months and use it every morning. Each bottle lasts me about 4-5 months, making it a great value. Unlike many vitamin C serums that leave your skin feeling tacky or sticky—or cause other products to pill—this one absorbs beautifully. I struggle with sunspots (thanks, Dad!), and this has faded them to the point of being nearly invisible. I have dry, sensitive skin and have had no issues using this product. While the recommendation is four drops, I tend to use more, applying it to my face, neck, and chest, then using any leftover on the backs of my hands. The serum has a lovely silky feel and a mild citrus scent that I really enjoy. One thing to note: the glass bottle and dropper require care. I accidentally dropped a dropper in my sink, and it shattered. Thankfully, I already had a backup bottle ready. At 57, I know the importance of following up with a good sunscreen, and I highly recommend doing so. Overall, this is an excellent vitamin C serum that delivers real results and is well worth the investment!
